Jennifer Lopez dons a badge in NBC's midseason drama Shades of Blue, in which she plays cop and single mom Harlee Santos (Mysteries of Harlee? Not quite.)

In the first-look trailer, which Lopez posted on her Facebook page Sunday, we learn that Harlee is having a tough time reconciling her obligations to the FBI and her emotional ties to her boss, Lt. Bill Wozniack (Ray Liotta), to whom she owes "everything."

Check out the sneak peek below. What do you think?
